FIELD OF THE INVENTION

[0001] The present invention relates to a slot set of a palm heldcompute for receiving multiple function cards simultaneously. Thereby,the palm held computer is suitable for function cards of different oridentical specification.

BACKGROUND OF THE INVENTION

[0002] A palm held computer (personal digital assistant) is amicrocomputer, wherein the user inputs from the function keys on thepanel or by a pen to select data or instructions thereon so as toperform related instructions.

[0003] Referring to FIG. 1, in general, a palm held microcomputer 60 hasa slot 65 at a back side thereof for being inserted by a function card80, such as SM cards (smart media card), MD cards (mini disk card); SDcards (secure digital card) or CF card (compact flash card). The powerof the function card 80 is from the inner circuit unit in the palm heldmicrocomputer 60. The function card 80 has a control unit 70 therein.The control unit 70 is communicated with the circuit unit as thefunction card 80 and the palm held microcomputer 60 are combined as anintegral body.

[0004] Since the palm held microcomputer 60 has only single one slot forusing a single function. A plurality of function cards with different orthe same specification can not be used at the same time. If functioncards of different specifications are to be read, it is necessary toupdate cards or download data.

SUMMARY OF THE INVENTION

[0005] Accordingly, the primary object of the present invention is toprovide a slot set of a palm held compute for receiving multiplefunction cards simultaneously, which comprises a personal digitalassistant and an adapting seat. The personal digital assistant has areceiving groove thereon. A bottom of the receiving groove is installedwith an electrically connecting terminal set. The adapting seat has areceptacle at a lower end thereof. The receptacle is communicated withthe electrically connecting terminal set. A plurality of slots areinstalled on the adapting seat. The bottom of each slot is installedwith a terminal seat communicated with the receptacle for being insertedby function cards of different or the same specification. If functioncards of different specifications are to be read, it is necessary toupdate cards or download data.

[0006] Another object of the present invention is to provide a slot setof a palm held compute for receiving multiple function cardssimultaneously. Thereby, the palm held computer is suitable for functioncards of different or identical specification.

[0007] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Referring to FIGS. 2 to 4, the slot set of a palm held computeraccording to the present invention is illustrated. The slot set of apalm held computer includes a machine body 1 of a personal digitalassistant (PDA) and an adapting seat 2.

[0016] The machine body 1 is installed with a display plate. A window 11and function keys 12 are installed on the plate. The inner circuit unitthereof has a function of storage. Thereby, the user may select desirednumbers and icons on the window 11 using the function keys 12 so thatthe object of storage and recording is achieved. The back panel of themachine body 1 is installed with a receiving groove 13 for beinginserted by the adapting seat 2. A bottom opposite to the receivinggroove 13 is mounted with an electrically connecting terminal set 14.The electrically connecting terminal set 14 is communicated with thecircuit unit 16. A battery cover 15 is installed adjacent to thereceiving groove 13. The battery cover 15 has batteries therein forsupplying power to the circuit unit 16.

[0017] The two lateral surfaces of the adapting seat 2 are formed withrespective sliding grooves 21 for being combined with the receivinggroove 13 of the machine body 1. A bottom of the adapting seat 2 isinstalled with a receptacle 22. The receptacle 22 is firmly secured to acircuit board 20. A plurality of adjacent slots are installed on theadapting seat 2. In the embodiment of the present invention, there arethree slots. The bottom of each slot 23 is installed with a receptacle22 communicated with the terminal seat 24 for being inserted by threefunctional cards (not shown), such as SM card, SD card, MD card, or CFcard. A recess 25 is formed between two sliding grooves 21 of theadapting seat 2. Thereby, the user may push the adapting seat 2 into thereceiving groove 13 of the machine body 1, or extract the adapting seat2 from the machine body 1.

[0018] Thereby, the palm held computer can be suitable for the functioncards without modification for function cards with differentspecifications.

[0019] Referring to FIG. 5, in the present invention, two slots 23, 23′can be formed on one lateral surface of the adapting seat 2.

[0020] Referring to FIG. 6, in the present invention, four adjacentslots 23 can be formed on one lateral surface of the adapting seat 2.

[0021] Referring to FIG. 7, in the present invention, one lateralsurface of the adapting seat 2 is formed with two slots 23 and atanother adjacent surface is installed with another two slots 23.

[0022] Thereby, the user may insert the function card into the slots 23(23′) of the adapting seat 2 at the same time. Thereby, the machine body1 may read data in the function card.

[0023] In summary, the present invention has the following advantage:

[0024] 1. A plurality of cards can be used on the adapting seat.

[0025] 2. It is unnecessary to update or download for function cards ofdifferent specifications.

[0026] 3. The user may select as required.

[0027] Although the present invention has been described with referenceto the preferred embodiments, it will be understood that the inventionis not limited to the details described thereof. Various substitutionsand modifications have been suggested in the foregoing description, andothers will occur to those of ordinary skill in the art. Therefore, allsuch substitutions and modifications are intended to be embraced withinthe scope of the invention as defined in the appended claims.
